The Best Engineered FPV Stack Yet? HDZero Halo Stack

We’re proud to introduce the HDZero Halo Stack – a complete powertrain solution featuring the new Halo 4in1 70A ESC and Halo Flight Controller, engineered for the demands of racing and freestyle FPV. For the first time, you can build a complete FPV drone using only HDZero electronics, without compromise. The Halo Stack makes the build effortless with its low-profile design and plug-and-play components—no soldering needed for VTX, RX, or ESC connections. This project represents months of engineering, testing, and real-world flight validation. Every detail—from the thick 3oz copper PCB layers, to the copper bar optimizing burst-throttle response, to the conformal coating—has been carefully designed to deliver power, reliability, and durability in even the harshest conditions. The new Halo ESC supports both BLHeli32 and AM32—because pilots deserve the freedom to choose the firmware that fits their style. A huge thank you to all the testers and pilots who helped shape this product. Your feedback and hard work made this possible.
